“I’m very happy to be here with this team at Chelsea,” said Koulibaly.
“It’s a big team in the world and my dream was always to play in the Premier League. Chelsea came first to get me in 2016 but we didn’t make it. Now when they came to me I accepted it because they really wanted me to come to the Premier League to play for them.
“When I spoke to my good friends Edou [Mendy] and Jorginho they made my choice easier.”
Todd Boehly, chairman and co-controlling owner, said, ‘Kalidou Koulibaly is one of the world’s elite defenders and we are delighted to be welcoming him to Chelsea. A great leader and an exemplary team player, Kalidou brings a wealth of experience and attributes that will benefit our squad and the club as a whole.’
